+1. Download and install Cygwin and put its `/bin/` directory on your system path.
+1. Install the Cygwin Packages: `apt-cyg install rsync make`
+    1. Download `gettext` 0.20.1 or superior and put its `bin` directory on your system path.
+        1. https://mlocati.github.io/articles/gettext-iconv-windows.html
+    1. If the Cygwin `/usr/bin/` directory exists, move all files from `/usr/bin/` to `/bin/`.
+       The problem with the `/usr/bin/` is that it should not exists. Cygwin should map/mount `/bin/`
+       into `/usr/bin/`, i.e., they should be the same directory.
+1. Download and install Python for Windows (not from Cygwin) and put `python.exe` (not `python3.exe`) on your system path.
+1. Download and install pip for your Windows Python (`python -m ensurepip`).
+1. Download and install rust (compiler), npm, git and put them your system path.
+1. Download and install the pyaudio wheel from: https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyaudio
+    1. After download the file for your Python version, you need to define the following environment
+        variable before running anki:

+    1. If there is not an wheel available for your Python version, you can built it from the source
+        following the installation instructions on: https://github.com/evandroforks/pyaudio
+        After building and installing portaudio, you need to define the following environment
+        variable before running anki:
+        `set "ANKI_EXTRA_PIP=python -m pip install git+https://github.com/evandroforks/pyaudio"`
+1. Open a `cmd.exe` (command prompt) on the anki repository and run the command `sh run`
+    1. Do not use `bash run` because it my call for Windows Subsystem for Linux
+    1. Do not use any Cygwin terminal as `mintty.exe` because the `rust lang` compiler does not work with them
